rlhis invention relates to a smoke consumer, and more especiallyto theclass of smoke abaters and soot removers.

The primary object of the invention is the t5 provision of a machine ofthis character, wherein the same is attached and coacts with the outletor smoke Hue of a furnace or the like, and when in operation, wil'lautomatically effect the consum tion of smoke or the abatement thereof,an the removal of soot from the Hue, thus avoiding the belching of smokefrom the chimney or stack, during the working of the furnace, and alsoavoiding the accumulation of soot within the Hue, thereby eliminatingthe cleaning of the chimney from the constant use of the furnace.

Another object of the invention is the provision of a machine of thischaracter, wherein on the starting thereof, the damper within the Hue ofthe furnace, which is normally open, will be initially, manuall closed,so that the spent products of com ustion w1ll be diverted from the Huethrough the machine, for the filtering of the same, to abate or removesmoke and other foreign matter, particularly soot, and when the machineis stopped, the damper or Hue will be automatically opened, therebyeliminating manual reopening of such damper or Hue.

' A further object of the invention is lthe provision of a machine ofthis character, wherein the construction thereof is novel in form, and

when in operation, will abate or cause the elimination of smoke issuingfrom the Hue of a furnace or chimney, and at the same time, willmaintain said chimney of Hue free from soot and foreign matter.

A still further object of the invention is the provision of a machine ofthis character, which is comparatively simple in its construction,readily and easily attached to the Hue of a furnace or the like,thoroughly reliable and eflicient in its purpose, strong. durable andinexpensive to manufacture and install.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts, as willbe hereinafter more fully described, in detail, illustrated intheaccompanying drawings, showing the preferred embodiment of theinvention, and ointed out in the claims hereunto appende lt is of courseto be understood that changes, variation and modifications may be madein the invention, as come properly within the-scope of the ap- 55 pendedclaims, without diverting from the spirit of the invention orsacrificing any of its advantages.

Referring to thev drawings in detail, A designates generally a portionof the smoke or spent products of combustion Hue of a furnace, which maybe of any ordinary, construction, and has arranged therein a swingingdamper B, which-is normally open, the damper being pivotally supportedcentrally within the Hue A. 9

Adapted to be attached to the Hue A is the smoke abater or consumer,and'sootremover, which comprises a box-like tank 10, supported uponuprights or legs 11, at the lower vcorners thereof, so that said tankcan rest, upon and elevated from, a foundation. The interior of the tankis suitably lined to provide a water reservoir 12 for containing a bodyof water 13, maintained at a predeter mined level through a Hoatactuated valve erable valve 19, so that the supply to the res,

eril'pir 12 from the tank 16 can be cut off at w1 Rotatably arrangedwithin the reservoir 12 is a cylindrical foraminous filter or screen 20,the axle 21 of which is journaled in the sides of the vtank 10, andoverhanging this filter or screen 20 from the top of the tank 10, is abaiile 22 which prevents smokeentering the tank at one side of -saidfilter or screen from escaping to the other side thereof, except bpassage through the filter or screen. Provi ed in opposite ends of thetank 10, contiguous to its bottom, are drain openings 23, each beingclosed by a removable plufr 24, and the removal of this plug permits thedraining of the reservoir 12, as will be obvious.

Supported at one side of the tank 10, above its top, is a table 25, thesupports of the latter being brackets 26, suitably secured to t-he tank.Upon this tableY 25, is secured an electric Vmotor 27, its drive shaft28 being provided with a Worm screw 29, meshing with a driven worm gear30, the same being equipped to constitute a pulley for a belt 31, whichis engaged with a pulley 32, fixed to the axle 2l of the filter orscreen 20, and in this manner, motion from the motor 27 is transmittedto the said filter or screen for rotation thereof.

Axially in alignment with the drive shaft 28 of the motor 27, and spacedtherefrom, is a fan casing 33 having therein a fan, not shown, operateddirectly from said shaft 28, and this casing 33 has its intake pipe 34ccmmunicating with the flue A of the furnace, while its peripheraloutlet pipe 35 opens into the tank 10 at one side of the filter orscreen 20, while leading from said tank 10, at the other side of thefilter screen 2() is an exhaust or outlet pipe 36, which opens into theflue A at a point beyond the damper B therein, the intake 34 of the fancasing 33 being located at the other side of said damper, or next to thefurnace head.

Connected with the pivot of the damper B is a weighted arm 37, thisbeing located exteriorly of the flue A, and its weight 38 is formed witha crank 39, pivotally engaged in a coupling 40, fixed to a proppingelement 41, the latter slidably maintained .upon a swinging terminal arm42 of a rocking shaft 43, supported in a bearing bracket 44 Fig. 3 fixedto the bearing 47 Fig. 2 of the drive shaft 28 of the motor 27, theshaft 43 at its other end being formed with a crank 48 pivotally engagedin a sliding trip 49, supported upon a swinging runway or guide 50,which is hinged at 51 to a fixed hanger 52 therefor.

At one side of the slide trip 49 is supported a releasing latch 53, thesame being adapted for engagement in a notch, 54 in the sliding trip 49,to maintain it normally against movement, and in this normal position,the damper B will be closed in the flue A.

Suitably supported upon t-he drive shaft 28 of the motor, is a governor55 having a series of weighted contrifugally actuated arms 56, thesewhen normally at rest, which is the contracted relation thereof, beingin the path of the latch 53, so that said latch 53 will be operated torelease the tri 49, thereby permitting the damper-B, w en closed, tobecome automatically open. The arms 56 of the governor 55, when themotor is traveling at propel' speed for the actuation of the fan 33 andthe filter screen 20, will be out of the path of the latch 53, so thatit will be undisturbed by the governor, and is only operated when thegovernor arms 56 are contracted or at rest position.

Normally, as has been stated, the damper B in the flue A of the furnace,is normally open, and in this position, the weight 38 is loweredtherefore to counter-act the weight, and to shift the damper B to closedposition it is necessary for an attendant, prior to the starting of themotor 27 for the operation of the machine hereinbefore described, tomanually shift the trip 49 to the position shown in Fig. 7 of thedrawings, whence the latch 53 will engage the trip 49 to lock it in suchposition. This movement of the trip 49 transmits motion through thecrank terminal 48 of the shaft 43 to the terminal arm 42, causing it toraise and through the element 41 and coupling 40 therewith, the crank 39of the weight 38 will effect the raising of said weight and through itsconnection 37 with the pivot of the damper B, the latter will becometurned to closed position in the flue A. Now, on the starting of themotor 27, the arms 56 of the governor 55 will instantly swing from restposition outwardly, thereby clearing the path of the latch 53 to beineffective thereon. The motor 27 started, the fan operates drawing thespent products of combustion from the flue A into the reservoir l2,whence the spent products-will be filtered through the filter or screen20, removing smoke therefrom and subsequently exhausted or deliveredthrough the outlet 36, back into the flue A, beyond the closed damperoint thereof, to be discharged from said ue or chimney that may beattached thereto.

When the motor is stopped, the governor arms 56 will come to rest or incontracted position, and just prior to the stopping of said motor, thesearms 56 in the position named, will act upon the latch 53, releasing it,whereupon the trip 49 will be caused to lower under the influence of theweight 38, and this influence of the weight swings the damper B to openposition automatically, which is the normal position of the damper.

The level of the water in the tank 10 is automatically controlled by theHoat actuated valve 14, which will be clearly obvious, so that a portionof the Hlter or screen 2O will be immerged. As the Hlter or screen 2Orotates, a screen of water thereon will be eHected within the tank 10for action upon the smoke admitted thereto, to eliminate the same fromthe Hue A, and the formation of soot therein.
